應用
Crimp seals with PTFE/silicone septa may be used to make specialized reaction vessel, by fusing them to top autosampler vials, in order to test the accuracy and reproducibility of the tetrabutylammonium fluoride and iodobenzene diacetateTBAF/PhI(OAc)2 method for detecting water in organic solvents. It may also be used to seal various samples, thereby isolating them from atmospheric CO2 for a period of atleast 1 month.

The potent dehydrating ability of difluoro(aryl)-lambda (3)-iodanes is exploited to develop a convenient (19)F-NMR-based aquametry method that is more sensitive than coulometric Karl Fischer titration. The key difluoro(aryl)-lambda (3)-iodane reagents are synthesized readily from commercially available and inexpensive precursors.
